Description:
Models of tree responses to climate typically project that elevated atmospheric CO₂ concentration (eCa) will reduce drought impacts on forests. We tested one of the mechanisms underlying this interact

Description:
Many species have the ability to resprout vegetatively after a substantial loss of biomass induced by environmental stress, including drought. Many of the regions characterised by ecosystems where res

Description:
Stomatal conductance (gs) is a key land-surface attribute as it links transpiration, the dominant component of global land evapotranspiration, and photosynthesis, the driving force of the global carbo
... More

Description:
Elevated atmospheric CO₂ (eCO₂) often increases photosynthetic CO₂ assimilation (A) in field studies of temperate tree species. However, there is evidence that A may decline through time due to bioche
... More

Description:
Leaf transpiration rate (E) frequently shows a peaked response to increasing vapour pressure deficit (D). The mechanisms for the decrease in E at high D, known as the 'apparent feed-forward response',
... More

Description:
The instantaneous transpiration efficiency (ITE, the ratio of photosynthesis rate to transpiration) is an important variable for crops, because it ultimately affects dry mass production per unit of pl
... More

Description:
Rising atmospheric concentrations of CO₂ (Cₐ) can reduce stomatal conductance and transpiration rate in trees, but the magnitude of this effect varies considerably among experiments. The theory of opt

Description:
Nocturnal water flux has been observed in trees under a variety of environmental conditions and can be a significant contributor to diel canopy water flux. Elevated atmospheric CO₂ (elevated [CO₂]) ca

Description:
Elevated atmospheric [CO₂] (eCₐ) often decreases stomatal conductance, which may delay the start of drought, as well as alleviate the effect of dry soil on plant water use and carbon uptake. We studie
